Which tool is used to test the continuity of fiber optic cables?

The fiber optic tracker is specifically designed for testing the continuity of fiber optic cables. This tool works by sending a light signal through the fiber and allowing the technician to detect whether the light successfully reaches the other end. If the light signal is present, it indicates that the fiber optic cable has continuity, meaning there are no breaks or issues in the cable that would prevent data transmission.

Choosing the fiber optic tracker aligns with the primary function it serves in the context of fiber optics, effectively ensuring that the cable is intact and operational before it is put into service. This is essential in maintaining the integrity and performance of fiber optic communication systems. Other tools, while useful in various electrical contexts, do not fulfill this specific purpose as effectively as a fiber optic tracker does.
